How about an installation in the warm sun (to make gasket more pliable)? Any tips would help...also with rear glass as well...Thanks!

P.S. Any opinions for cherry bombs on a very red, close to stock truck??

If you are re-using your original windshield, the gasket will fit perfectly although it may be difficult to install being new. The warm sun idea should help. The problem is with the cheap foreign windshields that are considerably thinner than OEM. The channel in the gasket is too big (actually the glass is too thin) and requires a lot of sealer to fill the gap. Also be cautious about the "blended" windshields with the blue stripe across the top. Many of the cheap brands have this, and the band is so tall it covers 1/3 or more of the upper windshield surface. Installed, the driver is looking through the blended section when driving.

If you need a new windshield, my experience is that a Pilkington windshield is a perfect fit, original thickness and has no waterfall distortion. But you'll probably need to shop for it by brand name.

As for glass installation, the flat 64-66 windshield is relatively simple.

. Fit the gasket on the glass with the vulcanized seam and the bottom center.
. Using something close to 1/8" diameter string or rope, feed it into the pinch weld cavity on the gasket with the ends at the top center. Leave about 6" or so on each end and tape them to the upper center inside surface of the windshield.
. Lubricate the gasket. Many recommend KY Jelly, or dish soap.
. Rest the bottom of the glass/gasket assembly on the lower pinch weld flange. While one person gently but firmly presses on the outside of the glass, pull the lip of the gasket over the pinch weld by pulling on the string until the gasket is seated all the way around.
. Fully seat the glass by gently slapping the outside surface with the open palm of your hand. Make sure you are not wearing any rings!

The back window is even easier, especially if you invest in one of the tools to install the locking bead.

Okay, thank you very much! I totally understand the technique. Have another question, though; do I use a sealer on the glass or the pinchweld (i.e. on the gasket or glass/pinchweld should i apply a sealer, or does the gasket seal the glass alone?) It is the original windshield. Also wanted to clarify that I should apply lube to the pinchweld seam after string is wrapped around the gasket inside the pinchweld seam. Thanks again!

First a correction. I must have been asleep, the ends of the cord need to be at the bottom center of the glass, not the top, since the bottom middle will be seated first.

On the lubrication question, I've changed quite a few windshields, and generally apply it to the gasket first since it will also soak into the string/rope and hold quite a bit. If generous enough it drips all over the pinchweld anyway. You can always add more during the install if needed.

When I lived in Idaho the windshield on my 1960 needed to be replaced three times. One shop used sealer in the glass channel, and that windshield leaked (a lot). The other two went in without any sealer and never leaked a drop. Not sure if it's the luck of the draw, how well the glass and gasket fit, or how well the labor got the windshield centered and completely seated.

The factory shop manual (for 1960) apparently loved sealer and states:

3. Apply a 3/16" x 1/2" ribbon of medium bodied sealer at the base of the pinchweld flange around the entire perimeter of the opening.

6. Seal the outside lip of the rubber channel to the glass with a minimum strip of 1/32 thickness weatherstrip adhesive between glass and lip around perimeter of glass.

7. Apply a 1/8" x 1/4" ribbon of medium bodied sealer to the flat of the windshield opening rabbel along the entire length of the pillar side and extending for approximately 6 inches beyond the upper and lower corners. (Again this is for a 1960).

8. Remove all excess sealer and adhesive with mineral spirits.

Since I've had better luck with no sealer, I'd be inclined to not use any.

It's difficult to know which advice is good and what isn't unless you can see the results of their work (even if you're doing the install yourself). The outfit that installed my leaky windshield also scratched my fender extensions, hood, and vent panel. The only reason I went with them was because they were billed as street rod specialists, the owner drove a 34 Ford, and claimed my truck would be treated like one of their own!

okay...thanks! i'm leaning toward no sealer..given the use of lube..I'll post my results...
